Title (EN) PRE-COMBUSTION CYCLE PRESSURISATION SYSTEM
(FR) SYSTÈME DE PRESSURISATION DU CYCLE DE PRÉCOMBUSTION
Abstract: front page image
(EN)A two stroke internal combustion engine (1) incorporating an asymmetric exhaust port/transfer port inversion device (2) characterised in that the device includes a hollow flap valve (100) adapted to pivot about a hollow pivot shaft (101) between a closed position and an open position wherein pivoting the device (2) to the open position as the piston (3) begins the compression stroke allows the transfer of air to continue after the leading edge of the piston has closed off the exhaust port (105) thereby advancing the timing of the exhaust port closing and extending the duration of air transfer from the crankcase primary compression chamber (103).
(FR)L'invention porte sur un moteur à combustion interne à deux temps (1) comprenant un dispositif d'inversion (2) orifice de transfert/orifice d'échappement asymétrique, caractérisé en ce que le dispositif comprend une vanne à clapet creuse (100) apte à pivoter autour d'un arbre de pivot creux (101) entre une position fermée et une position ouverte, le pivotement de dispositif (2) à la position ouverte lorsque piston (3) commence la course de compression permettant au transfert d'air de continuer après que le bord avant du piston a fermé l'orifice d'échappement (105), avançant ainsi la temporisation de la fermeture de l'orifice d'échappement et étendant la durée de transfert d'air à partir de la chambre de compression primaire de carter (103).
